<!-- loggerUserManager日志管理 -->
<filter>
<filter-name>set loggerUserManager</filter-name>
<filter-class>com.xxxx.LoggerUserManager</filter-class>
</filter>
<filter-mapping>
<filter-name>set loggerUserManager</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
-------------------------------------------------------------然后是指定路径的类---------------------------------：
import java.io.PrintStream;
import java.text.SimpleDateFormat;
import java.util.Date;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class LoggerUserManager implements Filter{
protected Logger logger = LoggerFactory.getLogger(getClass());
@Override
public void doFilter(ServletRequest request,
ServletResponse response, FilterChain chain)
throws IOException, ServletException{
chain.doFilter(request, response);
try {
HttpServletRequest req = (HttpServletRequest)request;
SimpleDateFormat formatter = new SimpleDateFormat(
"yyyy-MM-dd HH:mm:ss");
Date currentTime = new Date();
String strDate = formatter.format(currentTime);//1.时间
String hostUser = req.getRemoteUser();//2.用户名
if(null==hostUser){
hostUser =" ";//没有就设置为空字符串
}
String url = req.getRequestURL().toString();//3.请求url
String params = req.getQueryString();//4.请求参数
logger.info("时间为："+strDate + "; 来自IP:" + hostUser +
" 请求了:" + url + "?" + params);
}catch (Exception e){
e.printStackTrace();
}
}
@Override
public void destroy(){
}
@Override
public void init(FilterConfig arg0) throws ServletException {
// TODO Auto-generated method stub
}
}
-----------------------------------------------------------------------------最后是log4j.properties文件配置路径--------------------------------------------------------------------
log4j.rootLogger=${rootlog}, stdout, logfile
log4j.appender.logfile.File=${application.root}/WEB-INF/logs/application.log
